Code-Projects Real Estate Property Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in version 1.0 of the Code-Projects Real Estate Property Management System. The issue arises in the '/Admin/User.php' file, where the 'txtUserName' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation of data, deletion of information, and access to sensitive data, posing a significant risk to system security and data integrity.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/Admin/User.php' with the 'txtUserName' parameter. The injection payload should include a time-based blind SQL injection payload, such as one that uses the MySQL 'SLEEP' function to demonstrate the injection.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
